BUG: Windows Update says I never checked for updates!!!

Today when I opened Windows Update, I saw a message with a red X tell me that
I never checked for updates! But this is false because my system is fully
updated.
In windowsupdate.log I see it found 19 updates ("Found 19 updates and 31
categories in search").
And also it downloaded the CAPICOM patch kb931906 (maybe because I've
installed live messenger 8.5 beta and live writer beta???)
I think there's a bug in the servers or in the windows update.
Has anyone got this bug?
